[R-390] Refinishing Knobs

[Cecil]

The process I use...

Glass bead blast the knobs to strip them and to add a nice finish for primer to grab onto.  I prime with zinc chromate and let them cure for a week or so in the air conditioned shop.  I then spray with a matte finish black paint...usually Rustoleum due to its durability.  I let that cure for a week or so and fill the lines with a white lacquer stick.  Comes out really nice.

I do the same with the frequency bezel and the meters...

Hope that helps....
